D miningwell 76mm* 3m 76mm*6m Drilling Rod for well mining
D miningwell provides leading strength and penetration rates for more productivity, excellent straightness and hole clean quality, get max drilling performance to save up fuel cost rate.
D miningwell can design and manufacture according to customers’ samples or drawings of the length. Our taper rod is made by high quality steel, through heat treatment so that it can be used for hard rock drilling, and transmit intensive impact energy into the rock with the least possible loss of energy. Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency.
There are many factors to consider when choosing a tapered drill rod. First, we need to see the material of the drill pipe and its shape and size. At the same time, we also need to consider the strength of the rock drill, the strength and hardness of the rock. If the hardness of the rock is relatively large, we need to choose a higher power rock drill and a tapered drill rod of good quality. In choosing tapered rod.
When drilling, we must first understand the diameter of the drilling tool, and the depth of the rock hole is also a factor that cannot be ignored. The drill rod should not only adapt to the drilling hole, but also choose a tapered pipe that is consistent with the interface.
